Abstract: A multi-band antenna includes a base plate of which a feeding portion, a connection section and a ground portion are connected with rear, front and left edges of the base plate respectively, a first radiating element connected with a right edge of the base plate and coplanar with the base plate, a second radiating element coplanar with the base plate and the connection section and connected with an upper portion of a left rim of the connection section with a free end thereof adjacent to the ground portion, and a third radiating element connected with a lower end of the left rim of the connection section. Wherein the second radiating element is apart located between the ground portion and the third radiating element.

Abstract: A probe connector includes an insulating housing of which a top protrudes upward to form a plurality of inserting pillars each defining an inserting hole vertically penetrating therethrough, and a bottom defines a plurality of fixing holes each vertically extending to be connected with a bottom of one inserting hole. A plurality of probe pins is inserted upward in the inserting holes through the corresponding fixing holes respectively. A shielding body made of metal defines a plurality of inserting openings arranged in accordance with the inserting pillars and each vertically penetrating through the shielding body. The inserting pillars each are inserted in one of the inserting openings with a top end of the probe pin stretching in the corresponding inserting opening, so that each of the probe pins is enclosed by the shielding body to make the probe pins separated from one another by the shielding body.

Abstract: A miniature hinge includes a hinge housing, a first cam having a shaft portion, and a plurality of first can protrusions provided with facing cam surfaces defining a valley-shaped portion and an aperture passing through the first cam, a second cam having a plurality of second cam portions with a plurality of opposite circumferential curved surfaces, a perforation passing through the second cam and a plurality of grooves formed on front end of the perforation to form an end hole, an elastic element received in the hinge housing and a hinge shaft having an axle, a circular board formed and a positioning seat. The positioning seat of the hinge shaft passes through the hinge housing, the elastic element, the first cam and the second cam. The hinge shaft is rotated in an angle in order to insert the positioning seat into the end hole of the second cam.

Abstract: The present invention provides a module connector including a housing having four sidewalls that define a chamber for receiving a module therein. Each sidewall defines a plurality of contact recesses. A plurality of contacts is accommodated in the contact recesses and electrically contacts with the module. Pull-out prevention slices are positioned on periphery of the housing. Each pull-out prevention slice has a pressing portion which extends into the chamber and presses on the top of the module downwardly, and an actuating portion which extends upwardly from the pressing portion and is adapted for being manually pulled outward. When the module is needed to be pulled out from the module connector, by pulling the actuating portion outward, the pressing portion is driven to move outward and upwardly with the result that the pressing portion departs from the module to make way to the module for the module being pulled out. Therefore, no special tool is needed, in turn, the module is avoided being scraped.
